Question

Which expression is equivalent to 14x − 7 + 3(2x − 5)? A) 6x + 12 B) 8x − 12 C) 20x − 22 D) 24x − 15

Answer 1

the awser is C she is correct thx =DD

Answer 2

The given expression is

`14x - 7 + 3(2x - 5)`

And we have to find the equivalent expression.

First we simplify the given expression by distributing 3 on 2x-5. That is

`=  14x-7+6x-15`

Now we combine the like terms, that is

`= 14x+6x-7-15 = 20x -22`

And that's the simplified expression. And hence the correct option is C .
